The advantage of locating the entry-for steamvat` the vertex portion of thegchamber 10 is thatit Ywill "have a maximum effect in warming the .entrynozzle`9 in its expansive movement -to the basev of -said conical vchamber. In its passage through-the restricted opening between the .end vof 'thisi nozzle `and the recess 17 in 'the headjlll theoil will be substantially reversed in'itsfdirection' of How.,

somewhat atomized, Econverted into v-a. thin flared jet surroundingtheentry nozzle and projected into the opposing-.flow ofsteam within the convergent end portion of this `chamber at a considerably increased velocity.

And here the oil, which has already'been reduced to a somewhat atonrized -state, will now be Vcompletely atomized by the steam `in itsexpansive movement from vthe vertex to thebase of said cone chamber. l In this movementl toward the dischargevportion of the device the resultant mixture willfol'low the'outer walls of the chamber and will therefore avoid the denser and oppositely moving oil It will now Vbe apparent that Irhave 'Lembodied all the essential features of an efficient and durable atomizing device in a very simple form comprising only two units and which is comparatively low in its cost of production. My atomizer is direct acting throughout, does not form carbon, and may beA .readilyk disconnected land cleaned, although I A have found that it requires yalmost no attention after it is installed.
